        摘要：The property advantages of composite biomaterials used in biomedical fields are summarized from the view of improved mechanical properties and adjustable degradation rate as compared with a singlecomponent material.The research progress of composite biomaterials, especially those organic/inorganic composites used as bone implant materials is mainly reviewed in this article.It is suggested that incorporation of hydroxyapatite nanocrystals into biodegradable polyester matrix may produce new-type bone implant material which possesses excellent osteoconductivity and desirable biodegradability.The related researches represent the new research direction of organic/inorganic composite biomaterials.

        摘要：The difference of interactions between macromolecules and small molecules is obvious.As a result, the condensed states and the properties of macromolecules are quite different from that of small molecules. In this paper, the importance of interactions between macromolecules and its influence upon both structure and properties has been discussed in following aspects:the strong interactions between macromolecules, the peculiar dissolving process of polymer in solvent, Mark triangle principle, characteristic temperatures, the unusual single-chain macromolecular condensed state, cohesive entanglement and supermolecular system.
